From Ulrich Hertlein, "Attached is a patch that introduces 'static_cast<unsigned int>' on some instances where
...
the code returns '.size()' of a std::vector. This caused some warnings when using clang++
on OS X."

Added corner dirty options to TerrainTechnique, added experimental code paths in GeometryTechnique for accounting for neighbouring corner tiles - optionally compiled out in this check-in.
...
Changed the normal computation in GeometryTechnique so that it doesn't include diagonals, thus avoid normal jumps at corners.

...
Implemented new update scheme of GeometryTechnique to avoid potential threading issues.
Added Terrain support to .ive.

From Jason Beverage, "I posted a question on osg users about resources not being properly released when using osgTerrain databases and multiple viewers are used a few weeks ago and I've found that at least part of the problem comes down to the fact that the nodes that are traversed by the GeometryTechnique are never actually added to the scene graph, and thus don't have releaseGLObjects called on them. I'm submitting a few changes that takes care of this by allowing the TerrainTechnique to provide a releaseGLObjects implementation. I've applied these changes in osgEarth and this example program no longer crashes on the second run, although I get corrupt geometry (see attached shot) which could be down to a driver issue. If I increment the context ID for the second viewer, I no longer get the corrupt geometry.
...
The attached changes are against OpenSceneGraph 2.8.2.
//Sample program. Run against an osgEarth or VPB database based on osgTerrain.
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
int main(int argc, char** argv)
{
osg::ArgumentParser arguments(&argc,argv);
osgViewer::Viewer* viewer = new osgViewer::Viewer();
viewer->setUpViewInWindow(100,
100,500,500);
osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFiles(arguments);
viewer->setSceneData( loadedModel.get() );
viewer->run();
delete viewer;
viewer = new osgViewer::Viewer();
viewer->setUpViewInWindow(100,100,500,500);
loadedModel = osgDB::readNodeFiles(arguments);
viewer->setSceneData( loadedModel.get() );
viewer->run();
delete viewer;

Reorginized the TerrainTile/TerrainTechnique dirty mechanism so that TerrainTile
...
now holds the dirty flag and enables/disables event traversal in response dirty
being set/unset. This allows terrain to be automatically updated in response
to Terrain scale and sample ratio changes.
